Abstract/OtherAbstract:

Rheographic studies of the lung and aorta have been performed on 20 patients with atrial fibrillation and on 30 normal individuals before and after Valsalva's manoever. The findings disclose a strongly expressed positive correlation between the duration of the cardiac cycle and the rheographic systolic index, a Vmax., a Vm and a negative correlation with the Q-a interval and the ab/RR of the lung and the aorta.
